PIC24F16KA304T-I/MV 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), data EEPROM, and a rich set of peripherals (ADC, timers, communication interfaces). The PIC24F family sits in Microchip's 16-bit MCU hierarchy between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/PIC32MM devices, offering a sweet spot of deterministic performance, low power, and rich peripherals. XLP variants extend battery life through deep-sleep currents in the nanoamp range, support peripheral operation while the core is halted, and add features like DSBOR, DSWDT, and RTCC that continue running in Deep Sleep.
Key features include 16 MIPS at 32 MHz from a 1.8V-3.6V supply, 12-bit ADC with 10/12-bit modes, hardware multiplier for DSP-like math, up to 39 I/O pins, and multiple communication peripherals including I2C, SPI, UART with IrDA and LIN support. The CTMU enables capacitive touch sensing without external components, while the mTouch solution simplifies implementation of buttons, sliders, and proximity sensors in low-power HMI applications.
Typical applications include wearable fitness and medical monitors, remote sensor nodes, IoT edge devices, battery-powered HMI with capacitive touch, and consumer electronics where sleep current and form factor dominate the BOM. The 48-UQFN package with exposed pad supports compact PCB layouts and provides an effective thermal path for the industrial temperature range.
When designing with this device, choose the correct PIC24F16KA304 variant suffix for your temperature grade (I = industrial, E = extended) and pin count. Always place a 100 nF decoupling capacitor within 3 mm of each VDD pin and tie the exposed pad to a solid ground plane for thermal dissipation and EMI suppression.

典型应用
PIC24F16KA304T-I/MV 适用于 6 应用s: Wearable Fitness & Health Monitors, Battery-Powered IoT Sensor Nodes, Capacitive Touch HMI (mTouch), Industrial Remote Controls & HMIs, Portable Medical Monitoring Devices, Smart Metering & Utility Endpoints.
Wearable Fitness & Health Monitors
The PIC24F16KA304T-I/MV is a strong fit for wearable fitness and health monitors thanks to its XLP deep-sleep current in the nanoamp range, 32 MHz / 16 MIPS core for sensor-fusion math, and 1.8V-3.6V VDD that accepts a single-cell Li-Ion battery directly. Its CTMU and 12-bit ADC support heart-rate (PPG) or temperature-sensor signal chains without an external touch or ADC IC, reducing BOM and PCB area. The 48-UQFN (6x6 mm) package enables slim wristband form factors, while 2 KB RAM accommodates lightweight Bluetooth-stack glue logic. In sleep-mode operation with DSWDT wake-up, the device can run for months on a single 100 mAh coin cell when sampling at sub-Hz rates.
推荐
Battery-Powered IoT Sensor Nodes
For wireless sensor nodes such as Zigbee or LoRa end devices, the PIC24F16KA304T-I/MV provides 16 MIPS of compute to run sensor-fusion, AES-128 encryption, and MAC-layer glue code, while XLP technology keeps sleep current in the nanoamp range. RTCC, DSBOR, and DSWDT operate in Deep Sleep, enabling years of battery life on 2xAA cells for utility metering or environmental monitoring. The UART (IrDA, LIN), SPI, and I2C peripherals connect directly to radios, sensors, and EEPROM, and the 12-bit ADC reads battery voltage for fuel-gauge functionality. The 48-UQFN package supports compact, low-profile PCB designs where board real estate is at a premium.
推荐
Capacitive Touch HMI (mTouch)
The PIC24F16KA304T-I/MV's integrated CTMU enables capacitive touch sensing for buttons, sliders, and proximity detection in industrial control panels, white goods, and consumer appliances. The 12-bit ADC paired with the CTMU delivers reliable touch performance through 3-5 mm of plastic or glass overlay, eliminating the need for an external touch controller. Combined with 16 KB Flash and 2 KB RAM, the device can host both the touch algorithm and a small graphical UI on an LCD. The 1.8V-3.6V supply range simplifies integration with battery or USB-powered appliances, and XLP features keep standby touch-scan power below 5 uA system-level.
推荐
Industrial Remote Controls & HMIs
Industrial remote controls, key fobs, and low-cost HMI panels benefit from the PIC24F16KA304T-I/MV's combination of LIN/UART connectivity, 12-bit ADC for analog controls, and ultra-low sleep current. The 16 MIPS core is sufficient for IR or RF protocol stacks (RC5, RC6, proprietary) and small display rendering. The 48-UQFN exposed pad offers excellent thermal dissipation for -40C to +85C industrial environments. XLP features like RTCC keep the device time-stamping events in sleep mode, while DSBOR and DSWDT ensure clean recovery from brownouts in noisy industrial power rails.
推荐
Portable Medical Monitoring Devices
The PIC24F16KA304T-I/MV suits portable medical monitoring devices such as pulse oximeters, glucose meters, and thermometers where low power, small package, and deterministic 16-bit performance are required. The 12-bit ADC captures biosensor signals with adequate resolution for SpO2 or glucose algorithms, while the 16 MIPS core runs the math. The XLP family's nanoamp sleep current extends battery life in always-on monitoring applications, and the 48-UQFN package fits in slim, pen-style enclosures. Designers should target a separate IEC 60730-class safety MCU or compliance verification for FDA/medical-grade systems.
推荐
Smart Metering & Utility Endpoints
Smart electricity, gas, and water meter endpoints rely on the PIC24F16KA304T-I/MV's deep-sleep nanoamp current, RTCC wake, and DSBOR/DSWDT supervision to deliver multi-year battery life on lithium primary cells. The 12-bit ADC reads sensor outputs (current transformer, optical, Hall-effect) with sufficient resolution for class-1 metering accuracy, while the UART/LIN peripheral interfaces to wireless M-Bus, Zigbee, or wM-Bus radio modules. Hardware multiplier accelerates FFT-based power-quality analysis, and 2 KB RAM buffers consumption profiles between radio transmissions. The industrial -40C to +85C range covers outdoor meter installations.

设计说明
Decouple each VDD pin with a 100 nF X7R ceramic capacitor placed within 3 mm of the pin and routed with wide, short traces to minimize inductance. Add a bulk 4.7-10 uF tantalum or ceramic capacitor at the regulator output to handle transient loads. For XLP applications targeting nanoamp sleep current, switch off any external pull-ups during sleep and use the internal pull-ups selectively.
Solder the exposed pad of the 48-UQFN package to a continuous ground copper pour for thermal dissipation and low-impedance ground return. Estimated: at 32 MHz and 3.3V, the device draws ~7 mA active; power dissipation is ~23 mW which is well within the package's thermal limits, but the exposed pad is still required for reliability.
Keep the trace between the IC and the ICSP programming header short and isolated from analog signal paths. Place the CTMU touch-sensing traces as short, narrow guarded traces with a ground hatch around them to suppress noise coupling. Route the 32 MHz crystal traces symmetrically with a grounded guard ring to avoid EMI.
Do not assume the PIC24F16KA304T-I/MV and PIC24F16KA102 share a pinout - the KA102 is a 28-pin device with fewer peripherals. Verify the datasheet pin table before PCB layout. Also, distinguish 'KA' (16 KB Flash) from 'KM' (different family with USB) and 'KL' (low-cost family) suffixes; the letter codes indicate different memory and peripheral configurations.
